Djplast, I understand these are some warnings I had read about a while back, as the "Blue" wax has certain properties that are supposed to keep it within the DME Jiffy Shot (and not all over the floor or in one's eyes) a more dense plastic should be retained as easily as the wax's properties do?
The "home brew" Injection molder assembly schematics were available on ebay, I happened to buy one before my purchase of the Jiffy. The folks at
www.hobbyinjectionmold.com sold them, and the completed machines. Not just anyone should actually build these things. I have chosen the DME because the only difference it has (other than holding more plastic than home brew) is the all in one package. AND
www.hobbyinjectionmold.com stopped making home brews because of potential lawsuits, no longer a registered domain!
I picked the jiffy for a lot less than the one in the link I posted earlier. Its just for example of whats available, and similar machines are or were up for grabs on ebay for around $320-450.
